工程目录如图所示，其中css、files、js、swfupload都是它所依赖的文件。用example.jsp来触发action。其中

flash要用swfupload_fp9.swf（之前一直用swfupload.swf，这是比较旧的版本所以触发action后只能发送一张，换成新的版本后可触发多次）

example.jsp代码如下：

官方版本的是用php或是jsp接收的，在把jsp改成action时特别痛苦，后来经过各种渠道得到了flash传图片时的文件域的name="Filedata".结果用struts2时就在action里命名相同的File Filedata；

PictureZoom.java代码如下：

  8. import?javax.imageio.stream.ImageInputStream;??
  9. import?java.awt.geom.AffineTransform;??
  10. class?PictureZoom?{??
  11. private?String?todir;?//?todir?处理后的图片存放目录??
  12. private?String?sysimgfile;?//?sysimgfile?处理后的图片文件名前缀??
  13. private?File?F;??
  14. public?PictureZoom(){}??
